There's an article about NR's plans in Rail this week (#765 p54).
It seems that work on site will start in April 2015, the contractor being Carillion Powerlines.
They will be using road-rail vehicles for the work, not a high-output system.
The 125mph design isn't explicitly named but seems to not be either Series 1 (140mph, as used on the GW scheme) or Series 2 (100mph, as used on the NW and EGIP schemes).
The masts are said to be of a new slimmer and cheaper design.
Power supplies will be at Sundon/Luton (upgraded), Braybrooke (Market Harborough), Trent and Chesterfield.
The overall cost is set at £1.3 billion (original estimate £0.9 billion).
The milestones are the same as have been published in the NR CP5 plan, with the first stretch to be completed being Bedford-Kettering-Corby by Dec 2017.
Derby/Nottingham is Dec 2019, Sheffield Dec 2020.
The existing OHLE between St Pancras and Bedford will be upgraded for 125mph running, but will not be completely replaced.
They will be making passive provision for future extensions (eg towards Bletchley and Doncaster/Moorthorpe), but none have been approved yet.
Only 4 platforms will be wired at Sheffield, and the tunnel northwards is not being wired.
That means the electric stock must be based to the south of Sheffield.
There will not be a direct connection to any other electrified route, except Thameslink.
There are indirect electrified connections from St Pancras to the WCML and ECML (and HS1).
This scheme was authorised in the CP5 HLOS (July 2012), so it is good going for NR to get the project off the ground within 3 years.
This makes the 4th concurrent major electrification scheme in progress (and has overtaken the TP scheme).
Let's hope for good progress, and early extension!
